Vikas Saurabh commented on OAK-3087:
------------------------------------
I think [~chetanm] concern was more around the way of iterating over revision
map to get 'current' value of type. As far as I know comparing latest value to
"disabled" a good check.

> While disabling property indices, avoids usage of those indices. But, they
> still maintain the data already stored under them. That data would keep on
> consuming storage space without serving any purpose. Also, it'd pile on
> mongo's id index.
> While one can delete index definition node to clear these nodes up -- but,
> it'd be really slow and a JCR based deleted would first create a HUGE commit
> while marking all documents under it as deleted. And, then the actual
> deletion would happen in next revision GC after 24 hours have past.
> Hence, it might be beneficial to have a low level api in oak-mongo.js, which
> simply removes the document from mongo altogether.
